## Request

- Base URL: `https://api.croma.run`
- URL: `https://api.croma.run/co/secop/bidders-search/v1`
- Auth: HTTP bearer

Search who bid on Colombian procurement processes, including the bidders that lost. Filter by process id or by a bidder's document to see either everyone who competed for one contract, or every process a company has bid on. This is the only published view of how contested a tender actually was.

**Dataset endpoint**: answers from the whole source in milliseconds and carries `as_of`.

## Headers

- `Idempotency-Key` string

## Request body

- object
  - `process_id` string: Optional process id from a search result (`id` on a process, or `process_id` on a bidder). Empty searches every process.

  - `platform` 'any' | 'secop_i' | 'secop_ii': Restrict to one system: `secop_ii` (the transactional platform, 2015 onward), `secop_i` (the publication register, 2004 onward), or `any` for both.
  - `year` integer: Optional calendar year. 0 searches every year.
  - `page` integer: 1-based page number for paginated results.
  - `per_page` integer: Results per page (1-100).
